Identification, quantification and analysis of observable anthropogenic debris along swiss river and lakes (IQASL)

IQASL is a project sponosored by the Swiss Federal Office for the environment to quantify shoreline trash along swiss lakes and rivers in the Rhone, Aare, Ticino and Linth/Limmat catchment areas. This is accomplished by conducting multiple small scale and discrete litter surveys throughout the river bassin. The majority of samples are taken from lakes.

What is a litter survey?

A litter survey is the identification and count of all objects found within a delimited area, in this study all surveys were bordered on one side by water. Each object is placed into one of 260 categories¹. The location, date, survey dimensions and the total number of objects in each category is noted.

Purpose of the surveys

The survey results help ALL stakeholders identify the items that make up the mass of trash found in the natural environment on the shores of Swiss lakes and rivers. The surveys answer the following questions:

  • What items are found?
  • How much is found ? (total weights and item counts)
  • How often are these items found?
  • Where do you find the most?

These are the most frequently asked questions and should be considered when determining any mitigation or reduction strategies.

The project is based on the following assumptions:

  • The more trash there is on the ground the more a person is likely to find
  • The survey results represent the minimum amount of trash at that site²
  • For each survey: finding one item does not effect the chance of finding another³

Purpose of this report

Summarize the results for the survey area and define the magnitude of those results with respect to other survey areas.

The survey results are presented as follows:

  • Total object count, total weight and weight of plastics
  • The most abundant objects from the survey area and all the other survey areas sorted by total object count
  • Pieces of trash per meter (pcs/m): the ratio of number of objects found to the length of the shoreline
  • Objects that were found in at least 50% of the surveys

Results: Aare survey area

Scope

The Aare source is the Aare Glaciers in the Bernese Alps of south-central Switzerland. The Aare is the longest river entirely within Switzerland with a length of 295 km and drainage area of 17,779 km2. Following the Aare Gorge, the river expands into the glacial Lake Brienz. The Aare is canalized at Interlaken before entering Lake Thun and exiting through the city of Thun.⁵ The river then flows northwest surrounding the old city center of Bern on three sides. Continuing west to Lake Wohlen Reservoir it turns north to Aarberg and is diverted west into Lake Biel by the Hagneck Canal, one of a series of major water corrections made in the 19th and 20th centuries connecting Neuchatel, Biel and Morat lakes through canalization. From the upper end of Lake Biel, at Nidau, the river exits through the Nidau-Büren Canal/Aare Canal.⁶

The Limmat and Reuss rivers⁷, two major tributaries converge into the Aare at the Limmatspitz between the cities of Brugg and Untersiggenthal in Canton Aargau.⁸ The Aare river ends in the north-western region of Koblenz, Switzerland where it joins the Rhine river which eventually terminates in the North Sea.

Survey locations, municipalities

For the period between 2020-01 and 2021-04, 13,858 objects were removed and identified in the course of 138 surveys. Those surveys were conducted at 49 different locations, including 4 lakes and 5 rivers. There are 34 different municipalities represented in these results with a combined population of approximately 492,414

The top ten most abundant items

Combined, the ten most abundant objects of the Aare survey area represent 65% of all objects found in the survey area. Of the most abundant objects in the Aare survey area, 9 are also among the most abundant when all the survey areas are combined.

  1. Cigarette butts and filters
  2. Glass or ceramic drink bottles, pieces
  3. Fragmented plastics
  4. Insulation: includes spray foams and foam board
  5. Expanded polystyrene
  6. Industrial pellets (nurdles)
  7. Styrofoam < 5mm
  8. Industrial sheeting
  9. Food wrappers; candy, snack packaging

The most abundant objects: results by water feature

Some objects are found throughout the survey area and some of those objects are found in all survey areas. Knowing which objects are most abundant and what those values are helps idenitify sources or zones of accumulation.

top

How often are these objects found?

Some objects are found often and in elevated quantities, others are found often and in small quantities and some times objects are found less often but in large quantities. Knowing the diffference can help find the sources.

Objects found in at least 50% of surveys AND among the most abundant objects found
Combined they had an average pieces per meter per survey of 1.39, a min of 0.02 and max of 10.0

Utility: percent of total objects collected

Utility: The utility type is based on the utilisation of the object prior to it being discarded. Objects are placed into to one of the 260 categories. Those categories are grouped according to utilisation.

For example, a piece of plastic would be placed into the category 'Fragmented plastics', depending on its size. However, a piece of plastic that was once a bucket and we know this because we are familiar with either the brand or the product, is placed in a code for buckets⁸.

  • wastewater: items released from water treatment plants includes items likely toilet flushed
  • micro plastics (< 5mm): fragmented plastic items and pre-production plastic resins
  • infrastructure: items related to construction and maintenance of all infratructure items
  • food and drink: primarily single use plastic items related to consuming food and drinks outdoors
  • agriculture: primarily industrial sheeting includes
  • tobacco: primarily cigarette ends includes all smoking related material
  • recreation: includes fishing, hunting, boating and beach related objects, excludes food, drink and tobacco items
  • packaging non food and drink: packaging or wrapping material not identified as food, drink nor tobacco related
  • plastic fragments: foam and plastic fragments of indeterminate origin and use
  • personal items: accessories, hygiene and clothing related

⁸ See the annex for the complete list of objects identified, includes category and group classification

Effective data

The data is submitted in two parts. If a survey is missing either part we check the paper records and update when possible.

All the surveys found a home in the dimensional data
These dimensional records have been dropped, there is no matching survey data:

('luscherz-plage', '2021-01-26').

Population profile

The samples come from a variety of locations. Certain locations were sampled at monthly intervals others through out the year. Almost 90% of the surveys come from lakes within the survey area, here we consider the number of samples and the pcs/m per survey rating for all lake samples in the survey area.
